A 51.6 mL dilute solution of acid at 23.85 degrees Celsius is mixed with 48.5 mL of a dilute solution of base, also at 23.85 degress C, in a coffee-cup calorimeter. After the reaction occurs, the temperature of the resulting mixture is 27.25 deg C. The density of the final solution is 1.03 g/mL. Calculate the amount of heat evolved. Assume the specific heat of the solution is 4.184 J/g*deg C. The heat capacity of the calorimeter is 23.9 J/deg C.
